Graphite boat

Our graphite crucibles manufactured using the high purity graphite and good quality material.All graphtie crucible we can make it according to your requirements and your drawing. any shape, any size, you can any choose it.

1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold
or silver ornaments, analysis of special type steel, sintering hard metal.
2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelry industry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles according to customer's requirement.
3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it will start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.
4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.

Graphite Crucible Features
1.Graphite crucibles has good thermal conductivity and high temperature resistant;
2.Using in high temperature process, thermal expansion coefficient is small ,it has resistance strain performance to hot and cold, Strong corrosion resistance to the acid, alkali solution;
3.Graphite composition of graphite crucibles are all using natural graphite;
4.Graphite crucibles should not immediately be placed it in the cold metal table after heating,in order to avoid to break for the rapid cooling.
5.High mechanical strength, thermal shock resistance is strong, long service life, etc

Graphite Crucible Application
Crucible are suitable for smelting copper, aluminum, gold, silver, lead, zinc, and alloy and other non-ferrous metal.
